How do I open a DAT file video?

Answer by  Sandz (12)

The best way is to use the program that created the file to open it. If that's not possible, video files can be opened by Windows Media Player. If not then using command prompt, change the extension of the file from. dat to. mpeg and open it with windows media.

If you are having a problem opening a. DAT video file, the simplest solution would be to find VLC media player and download it. VLC generally plays all types of file extensions. If you do not want to do this, you can download the correct codecs to support it in your current media player.
